How do you set good habits without them turning compulsive?

For years I’ve been struggling with trying to put together a routine for myself. I always end up filling my time with things that pertain to others. I see my friends all day, I like to see my boyfriend a lot (even though it’s only a weekend to weekend thing), and I’ll scroll social media. When I go on social media I tend to look at people who is no longer in my life. With this, I’ve come to a realization recently that I’ve put others over my own needs. I barely take my meds regularly because I feel like I’m constantly busy at peoples events, hanging out, or work. I don’t want kids but I’ve grown up in a family the idolizes the nuclear lifestyle despite not having it, and my boyfriend wants kids, so I feel like I’ve put myself in a position to lose my idea of what I want. Sometimes I don’t even know if I want to be with a man. I feel sometimes that people will leave me if I just do what will work for me. I could put down my drink and I think of how it will affect others, not myself. I’ve always wanted to travel and get out but I know my boyfriend wants to stay with his family so I put it on the back burner. I’ve started to get anxious about me losing out on my life and what I want to do. It makes me think I’ve always lost out on so many opportunities. I want to try to start small. Making sure I have a good routine for myself that I won’t break and then try to apply that discipline to the rest of my life. I’m just not sure how.

So maybe the title wasn't the best to to put it but when you guys start having obsessive thoughts how do you stop them before it turns into compulsions and anxiety?

I cannot for the life of me stop ruminating or checking how I feel about thoughts or focusing on thoughts or creating more thoughts. I feel like I’m losing my mind. I want to scream. I try not to ruminate about the thoughts, but trying not to just makes me think about them more. I try not to check, but somehow, I still check. I want to let a thought sit in the background, but the more I try not to focus on it, the more I end up focusing on it. I don’t want the thought to expand because that feels like engaging with it, but I can’t just stop it from expanding. It feels impossible. People keep saying I’m in control of my compulsions, and maybe that’s true for the physical ones. But when it comes to the mental compulsions, I swear I have no control. It feels like I’m missing something that everyone else seems to have, like there’s some tool they’re using that I don’t have. Controlling mental compulsions has never felt possible for me. I’m starting to fear them. And every time someone says I’m in control and can just choose not to do them, I end up beating myself up even more when they happen. Or when I *choose* I guess. I don’t know anymore. If this is my fault, if I’m responsible for this, then what does that make me? I feel like a monster. I am at my wits’ end. How am I supposed to control mental compulsions when it feels like they control me? I freak out when they happen. They don’t bring me relief, they just make me panic. I want it to stop so bad.
